The device went on sale last week after having been delayed from its original 2017 release date.
It's worth noting that, in our own testing with HomePod in a number of places and on a range of different surfaces, we've not observed any issues with left-behind rings.
Should the blemish remain, Apple suggests that you gently wipe the surface with a soft damp or dry cloth or to "clean the surface with the furniture manufacturer's recommended cleaning process".
John Birchman tweeted, "Wait, so Apple's Home Pod is leaving marks on wood surfaces treated with oil or wax?"
The Guardian found that the HomePod did not leave marks on glass, Formica or plastic-coated reconstituted wood commonly used in flat-pack furniture.

"It wasn't the end of the world for us".
The Apple HomePod may permanently damage wooden furniture if the Siri-powered smart speaker is placed on top of it. Apple has confirmed the problem, which is the latest entry in the growing list of issues with the device.
Apple made a big deal about the sound quality its HomePod would produce. It depends on what the surface is it's placed on, of course, with certain types of wood being problematic.
"But the HomePod appears to need contact with the surface that it's on to resonate and create the powerful bass". Hence the problem can't be solved by just putting a cloth underneath it.
However, it seems there are still some issues that Apple didn't see fit to warn us about. According to Pogue, the majority of those in attendance said the Sonos One was the best, closely followed by the Google Home Max.
"Anyone who runs into this should be outraged", wrote Daring Fireball's John Gruber. I am now going to invent and sell a iCoaster for $49.99. If so, that could hamper Apple's efforts to catch up to less expensive internet-connected speakers from Amazon and Google that had a head start in the still nascent market.
